1-4-1 Dual Channel Memory Conguration

This motherboard provides four DDR3 memory sockets and supports Dual Channel Technology. After the

memoryisinstalled,the BIOSwillautomaticallydetectthe specications andcapacityofthememory. En-

abling Dual Channel memory mode will double the original memory bandwidth.

The four DDR3 memory sockets are divided into two channels and each channel has two memory sockets as

following:

Channel 0: DDR3_1, DDR3_2

Channel 1: DDR3_3, DDR3_4

1-4 Installing the Memory

Read the following guidelines before you begin to install the memory:

• Make sure that the motherboard supports the memory. It is recommended that memory of the

same capacity, brand, speed, and chips be used.

(Go to GIGABYTE's website for the latest supported memory speeds and momery moudles.)

• Always turn off the computer and unplug the power cord from the power outlet before installing

the memory to prevent hardware damage.

• Memory modules have a foolproof design. A memory module can be installed in only one direc-

tion. If you are unable to insert the memory, switch the direction.

Due to CPU limitations, read the following guidelines before installing the memory in Dual Channel mode.

1. Dual Channel mode cannot be enabled if only one DDR3 memory module is installed.

2. When enabling Dual Channel mode with two or four memory modules, it is recommended that

memory of the same capacity, brand, speed, and chips be used for optimum performance. When

enabling Dual Channel mode with two memory modules, be sure to install them in the DDR3_1 and

DDR3_3 sockets.
